Overcoat pen acrylic black 4.9g

Product Overview

The CircuitWorks Overcoat Pen CW3300BLACK from CHEMTRONIC is a pen dispenser with a modified acrylic conformal coating in black. The product comes in a pen size of 4.9 g (0.16 oz.) and has a declared shelf life of 2 years. The cured coating is descriptively stated to provide protection against short circuits, moisture, abrasion, and fungus.

Features

• Acrylic-based conformal coating in a pen dispenser (black)
• Resistivity: >1×10^12 ohm-cm
• Dielectric breakdown: >500 volts/mil DC
• Tack-free time: < 5 minutes
• Room temperature dry: 5–10 minutes; recommended heat cure 5–10 minutes at 200°F (93°C) for improved chemical resistance

Documentation

Product data and technical specifications are specified by the manufacturer and can be found in the manufacturer's datasheet. See datasheet from the manufacturer

Typical Applications

The official product information directly states the following application areas:

• Circuit Board Manufacturing
• Data Communications
• Aerospace
• Instrumentation
• Controls
• General Maintenance and Repair

Application and Usage Notes

The product should be applied after soldering, as the material decomposes above 270°F (132°C). For optimal adhesion, cleaning with a suitable board cleaner (e.g., the manufacturer's Electro-Wash) is recommended. The Overcoat Pen dispenses by pressing the body of the pen and pressing the tip onto the surface. Thinning is usually not necessary; propyl acetate can only be used if needed in bulk form. Removal can be done with acetone according to technical guidelines.
